frequency of 2 hours post glucose load hyperglycemia in subjects with normal fasting glucose

ABSTRACT

The prevalence of impaired glucose tolerance [IGT] and previously undiagnosed diabetes mellitus [PU-DM] in variety of ethnic group has been well documented. Limited information, however, is available about the presence in Iraqi population. The aim of this study is to investigate the prevalence of the glucose intolerance and undiagnosed diabetes among healthy adult population. A total of 918 members of the general population of Baghdad city were studied. They presented different age groups [ranging from 20 to 60 years]. All subjects were in good health, and had normal fasting serum glucose levels [<6.1 mmol/L]. For assessment of hyperglycemia, all subjects underwent an oral glucose tolerance test. Among 918 subjects [401 males and 517 females], 19.0% males and 16.8% females had IGT. The prevalence of PU-DM was 1.2% for males and 5.6% for females. The prevalence increased with age in both genders. IGT and PU-DM were more commonly seen in obese subjects than in normal weight subjects [IGT 24.5% vs 11.9%] and [PU-DM 6.3% vs 1.9%]. This report on the IGT and PU-DM from Baghdad population showed a high prevalence of these disorders
